For the computer illiterate out there, please don't go downloading malware posing as bittorrent clients.
Please don't use it to grab anything pirated unless you know what a VPN is and know which ones are trustworthy.
I'm on Linux, if you want a good multiplatform client, qBittorrent works well. (coincidentally it starts with a Q)

It's being used as a home entertainment system on an 11-12 year old computer with a budget GPU upgrade (Rx570) and it runs 4K like a charm.
It's good because it's like an unfucked version of Ubuntu so most Ubuntu software and wiki solutions work and Mint has a large user-base as well. It is an easy install and works out of the box. I installed KDE plasma after setup as a desktop environment because it looks so modern and clean and is yours to make your own with configuration. Manjaro is also a good distribution if you want a rolling release (updated regularly) and has some cool features (change kernel - no shutdown) and I would probably still be on it if not for HD failure. Thought I would try Mint and found that it would be very noob friendly and have just stuck with it.
My single gripe with all of Linux is that there is no graphical applet (GUI) to control your AMD video card under Linux at all. It's only a problem if you are trying to run triple monitor resolutions and crossfire rigs like my gaming PC. Fucking around in console to change super-resolutions and monitor configs is a pain and some very specific and hard info to even find.
